There can be no equivalence.
A tonne is a measure of mass. A cubic metre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider a cubic metre of air. How many tonnes? Next consider a cubic metre of lead. How many tonnes?
The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
There is 1 kilolitre in one cubic metre.
That depends on the pressure and temperature of the air in the cubic meter. Any time you change the pressure or the temperature of a gas, you change the number of molecules in one cubic meter of it.
Of water one tonne
a cubic meter is one meter cubed or to the 3rd power.
Well you would have to know how wide you want to make it and also what it is. If it is water one metric ton would be one cubic meter. Just take the cube root of 100 million and multiply by one meter and you should have it.
1.2 metric tons equals 1 cubic meter of Fly ash (one of the residues of coal combustion).
At room temperature and 1 atmosphere, the mass of one cubic metre of water is 0.998 207 1 tons.
1000 kg or roughly 500 lbs.
The weight of 1 cubic meter of road base can vary depending on the specific material and density. On average, road base material typically weighs around 1.5 to 2.5 tons per cubic meter. It's recommended to check with your supplier for the exact weight of the road base you are using.
One problem in answering this is that figures for the density of tar are all over the place; apparently there are different types or grades and some of them are denser than others. However, approximately speaking, most types seem to fall somewhere between one and one and a quarter tonnes per cubic meter.
400kg
One tonn
Cubic meters measure volume, tons measure either mass or weight (depending on whether you mean metric tons or US tons). You can't convert between the two without specifying a material. One cubic meter of water has a mass of just about one metric ton (which weighs almost the same as a US long ton).
One cubic meter = 1,000 liters.
There are 1000 liters in one cubic meter.
There are 35.3 (35.3146667) cubic feet in one cubic meter.
One cubic meter equates to 61,023.74 cubic inches.
